This read-only true/false value indicates whether the traffic statistics counters reported elsewhere in this table for this adapter are actually accurate, since some adapters can't report statistics reliably. An admin checks this before trusting error and traffic counters for a given physical adapter in troubleshooting. For example, if this reads false(2), an admin should not draw conclusions from that adapter's collision or error counters since the vendor's own agent says they aren't trustworthy.
